PUMPED STORAGE PLANT (PSP) AND RIVERBED WATER WHEEL OF HYDRAULIC POWER UNIT

摘要

FIELD: power engineering.;SUBSTANCE: pumped storage plant on plain streams comprises riverbed hydraulic power units, including axial pumps, which are rotated by riverbed water wheels via multipliers. Riverbed hydraulic power units serve for filling of an upper accumulating pond made in the form of a water reservoir with dam walls along the perimeter. Upper and lower accumulating ponds are connected to each other by discharge pipelines with pumps-turbines in the lower part connected mechanically with electric motors - generators in a turbine room. The upper accumulating pond covers a river bed by half.;EFFECT: prevention of flooding of plains and land plots, free navigation and fish passage along entire length of a river, increased depth of a fairway and higher speed of water flow.;5 cl, 11 dwg
